And that's where it breeds.

Do frogs breed in this water?

Because dragonflies need fresh water to breed.

The dragonflies are here now. They're breeding there.

They reproduce. That's population biology 101.

Creation of the Centre for Research into Human Reproduction, 1987

This was published after he died his sort of unfinished notes on self reproducing machines, what it takes to get the machines sort of jump started to where they begin to reproduce.

Those blooms are generating other kinds of chemicals.

Learn to multiply, thickening in places ...

And they are breeding in the rains of Africa.

This is a clonal tree as well.

Pollen is a flower's way of making more flowers.

That is to say, they specialize with respect to reproduction.

A few months later they return to their breeding grounds in the Arctic.

Did he compare it to animal breeding?

Penalties are consequently laid down for the improper production of embryos and their development outside a woman apos s body, the genetic manipulation of germ line cells (interference with the cell apos s make up, thereby affecting future generations), cloning chimera or hybrid creation.

These same infections create harmful algal blooms.

Of the ones that stayed, their reproductive rate declined.

And with the fishery, the entire reproductive ability of the species goes extinct.

Fertile biology of development of vertebrates (amphibians)

They assume that their problem is solved.

What's happening is they are breeding in the monsoon rains here.

And I said, Yeah. You know, I'm not really up on my frog reproduction that much.

The survivors that do get through produce this world of crocodile like creatures.

It's the one thing we insist on doing for ourselves, is reproduction.

Reductions in breeding populations of three seabird species in one Subantarctic island were recorded.

I saw birds that breed in Greenland, in the Gulf.

That's the Heddaby face. Inbred for centuries. Appalling.

Most Medusa jellies make special structures called polyps, that simply bud off babies with no need for sex.

Nematode worms showed a significant number of mutations compared to control specimens but no unusual reproductive behavior.

It's the mystical moment where life regenerates itself, over and over again.

They breed in the high arctic, and they winter down in southern South America.

My story is actually not about plant propagation, but about pollen itself.

But inevitably, these tumors progress towards being enormous, ulcerating tumors like this one here.

They give birth inside the ice, and they feed on the Arctic cod that live under the ice.

They're coming together. That could be tuna sex and there it is.

And a pig disease, a pig virus, and a human virus can both proliferate, and because of their kind of reproduction, they can combine and produce a new virus.

We can also see blooms of bacteria, blooms of viruses in the ocean.
